  • Patent number: 10288339
    Abstract: The present invention provides a geared motor in which a motor lead can be routed within a case to a position set apart from a motor, and a damper device. In the geared motor that is used in the damper device, the case is provided with a motor lead passage that extends in the Y-direction through a position flanked, in the Z-direction, by a side plate part of a case trunk part and the rotation axis of a driving gear that is included in a gear train. It is therefore possible, with the Z-direction positions of a plurality of motor leads being defined, to extend the motor leads in the Y-direction. The Z-direction dimension of the geared motor can then be reduced because the motor leads will then partially overlap the drive gear in the motor lead passage as viewed from the X-direction.

  • Publication number: 20190080211
    Abstract: A magnetic card reader is provided and includes the holder which is movable both in the card-inserting direction and the card-ejecting direction in the card pathway. The magnetic card is held in the holder which is energized in the card-ejecting direction. Therefore, when the card latch lever is retracted, the auto eject operation of the magnetic card is implemented. The distance between the card-receiving surface on the holder positioned in the insertion-waiting position and the reading-writing position in the X direction is longer than the length from the edge of the magnetic card on the back side X2 to the edge of the magnetic data recording range on the front side X1. Therefore, the magnetic card is prevented from hitting the card-receiving surface and therefore from receiving impact while the magnetic data recording range on the magnetic card is passing the reading-writing position.
